Evaluating the contribution of a metal independent aldolase to resisting nutritional immunity
… immunity, is the sequestration of the essential metals manganese and zinc. An important component of this defense is the metal binding host protein calprotectin, which inactivates metal- dependent bacterial enzymes. The ability of Staphylococcus aureus to cause infection suggests that it has …

The impact of metals and other stress factors on microbial ammonia oxidation physiology and isotope effects
… oxidizing organisms (AOO) require the trace metal micronutrients copper (Cu) and iron (Fe) for growth and metabolic catalysis. Ammonia oxidation is directly affected by pH in regulating the relative availability of ammonium (NH4+) and NH3. Also, photoinhibition of AOO is widely reported. The …

Describing the Cell Biology of Saprolegnia parasitica: Role of Metals and Respiration
… how S. parasitica responds to fluctuations in metal availability at the physiological and mitochondrial levels. This study investigates the impact of copper and iron availability on Saprolegnia parasitica growth, metal uptake, and respiratory function. We cultured S. parasitica in chemically …

Using Silicon Isotopes to Trace the Biogenic Silica in the Southern Ocean
… factors (temperature, light, and trace metal) provides a promising method for understanding how Si and C fluxes will change in response to future climate change. The Si cycle in the Southern Ocean was investigated using an isotopic approach in incubation experiments and the natural …
